Shoes; and I do hereby declare the follow ing to be a full, clear, thereof.

My invention relates to brake-shoes and has special reference to what are 'known'as cast brake-shoes, in which the body or braking portion of the shoe is formed of cast metal, such as cast iron, and provided with wire backs cast into such body.

The object of my invention is to provide a cheap, simple and e'liicient form of this class of brake'shoes, in which the lug or fastener for connecting the shoe to the hanger to support the shoe can be applied to the wire back easily and quickly, and will be securely held in place when the material is cast around the same and said back.

To these ends my invention consists, gen erally stated in the novel arrangement, construction and combination of parts, as hereand exact description inafter more specifically setforth and described and particularly pointed out in the claims.

To enable others skilled in the art to which my invention appertains to construct and use my improved brake shoe, I will describe the same more fully referring to the accompanying drawing, in which Figure 1 is a top plan view of a brakeshoe embodying my invention. Fig. 2 is a side view of the same partly in section. Fig. 3 is a view oi a portion of the back for the shoe, showing lug in section. Fig. 4.: is a cross-section on the line l1 of Fig. 1 looking in the direction of the arrow.

Like symbols of re'ference herein indicate like parts in each of the figures of the drawing.

As illustrated in the drawing 1 represents the usual approved formof a brake-shoe which has its body 2 formed of a frictionally material, such as cast iron, a composition of matter specially prepared or any other suitable material, and to which material a back 3 formed of longitudinal and crosswires or rods 4L- and 5, respectively, is connected, as hereinafter described.

The supporting lug or fastener 6 for connecting the brake-shoe 1 to the usual hanger Specification of Letters Patent.

or brake-head a by the key Z), shown in Fig. 2 in the usual manner is formed of the usual ductile sheet metal and bent to the usual approved form and shape in any suitable ianner. This fastener 6 when so formed has a body portion 7 and supporting legs or standards 8, which are tapered outwardly from said body and the ends of the same are bent to substantially a right angle to said standards, as at 9 to form bearing portions on said fastener.

In the formation of my improved brakeshoe 1, the wires or rods 1 and?) to form the back 3 are cut to the proper size and such cross-wires 5 are preferably secured to one side of the longitudinal wires 4 by electric welding at their intersections, after which the lug or fastener 6 as formed is connected to such backby passing the bearing portions 9 on the same between the two outer Wires 4: on each side of the shoe and inserting the outer wires 4 on each side within seats or notches 8 in the standards 8 adjacent to said portions, so that such wires will rest upon said portions. WVhen the lug or fastener 6 is thus placed on the wires or rods 1 and centrally of the back 3 formed by such Wires and the wires or rods 5, it is locked in such position by bending or compressing the outer wires 4 inwardly as at 4c. The back 3 is now ready for being attached or secured to the body 2 of the. shoe 1 by placing such back in a mold, so that it lays against one side of the mold by its wires 4 coming in contact with said side, and while being held in place in any suitable manner, the moltenmetal to form such body is poured into such mold and around the wires 4 and 5 and bearing portions 9 which not only forms such body but will envelop the wires 5 and such portions and will thus lirmly anchor such back on to the moving face or body of such shoe.

It will thus be seen that my improved brake-shoe will have its lug or fastener so connected to the same that it will be securely, firmly and positivelyheld in place, more particularly in the use of such lugs in connectionwith backs formed of wires or rods for such shoes, while such fastener can 1 sent a more finished appearance than where the ordinary meshed wire cloth is used for such backs, while in casting the shoe the wires as thus arranged will lie fiat against the mold and by reason of the wires being secured at their inter-sections through welcb ed joints such wires will be rendered immovable, will be a reinforcement to the shoe and will render the shoe less liable to break, while in case of breakage, the pieceswill be held to the back and thereby prevent the same or parts of the same from falling down on to the tracks and causing wrecks by-the derailment of the car.

It will be obvious that different forms of backs, rods or wires can be used, and, that the number of the longitudinal wires or rods can be varied, while various other modificm tionsand changes in thedesign, application and construction of my improved brakeshoe may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.

hat I claim as my invention and desire to secure by Letters Patent is -1. A brake shoe including a body member, rods secured to the back thereof, and a supporting lug secured to the rods, said rods being formed to provide means for preventing longitudinal movement of the lug.

2. A-brake shoe including a bodymember, rods carried by the back thereof, a supporting lug, and legs formed on the lug for engagement with the rods, said rods being formed to provide means i'or engaging the legs and holding the lug against longitudinal movement.

3. A brake-shoe comprising a body havand means formed integrally with said rods for engaging said legs forpreventing longi tudinal movement or the lug.

5. A brake-shoe comprising a cast body having its back provid having its back provided withrods cast into i 6. A brake-shoe'comprising a cast bodyh'aving its back provided with rods cast into the same, and a-supporting lug having legs provided with notches and means formed on the rods for holding the lug against longitudinal'movement, said means being engageable in the notches.

7. A brake-shoe comprising a cast body d with rods cast into the same, a supporting-lug having legs provided with notehes'for engaging with said rods-to connect the same thereto, and

fastener thereto.

bent portions in saidrods 'for locking said 8. A brake-shoe comprising a cast body having its backf provided with I rods; cast into the same, a supporting lug having legs provided with notches for engaging with said rods to connectthe same thereto, bearing portions on the ends of saidlegs for engaging with said rods, and means for locking said legs on said rods to nrevent longitudinal movement of said fastener on said rods. r V

9. A brake-shoecomprising a cast body having its back provided with longitudinal and cross-wires cast into the same, said cross-wires being onthe inside of said longitudinal wires andintegrally secured to the same .at their intersections.

- 10. A brake-shoe comprising a, cast body having its back provided with longitudinal and-cross-wires cast into the same, said cross-wires being on the inside of said longitudinal wires and Welded to the same at their intersections. r V 11. A brake-shoe comprising a cast body having its back provided with longitudinal and cross-wires cast into thesame, said cross-wires being on the inside of said longitudinal wires and electrically welded-to the same at their intersections; v In testimony whereof,I the saidMoRLEY PUNSHQU REYNOLDS, have hereunto set my hand.
